1. To prevent corrosion caused by heating during welding, the weld length should not be too long, about 20% shorter than that of carbon steel welding rods. The arc should not be too long, and rapid cooling between layers is recommended, with narrow weld beads.2. Stainless steel pipe fittings harden

Seamless steel pipes are an important material widely used in petroleum, natural gas, automotive, construction, machinery, power, and chemical industries. Unlike welded pipes, seamless steel pipes are made by piercing a single piece of round steel, resulting in a surface without weld seams, hence th

First, how to inspect plastic-coated steel pipes? Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, or plastic-coated composite steel pipes, are steel-plastic composite pipes with a steel pipe base. A layer of plastic anti-corrosion coating is fused to th

Spiral welded steel pipes are mainly used as fluid pipes and piling pipes. After manufacturing, if the spiral welded steel pipe is used for water transport, anti-corrosion treatment is generally applied to either the inner or outer surface. Common anti-corrosion treatments include 3PE anti-corrosion
